Looking at FIGS. 3-5 , a system 36 for loading, shifting, and stagingobjects is provided, in accordance with an embodiment hereof. FIG. 3primarily depicts one end 38 of the system 36. FIG. 4 primarily depictsan opposite end 40 of the system 36. FIG. 5 primarily depicts anunderside 35 of the system 36. In one instance, the system 36 may beused in a logistics network. For example, the system 36 may beincorporated into a mobile transport, e.g., a delivery vehicle, e.g.,one that operates in the logistics network. The system 36 is configuredto receive, shift, and stage a plurality of storage structures 44, asshown in FIGS. 3-5 . The storage structures 44 may be used to transportobjects, e.g., parcels or packages, to designated destinations, e.g., inthe logistics network. The system 36 shown in FIGS. 3-5 is intended torepresent one example configuration. However, many other configurationsare contemplated herein.

Looking specifically at FIG. 3 , a loading mechanism 42 is shown, inaccordance with an embodiment hereof. The loading mechanism 42 islocated at the end 38 of the system 36. The loading mechanism 42 isdesigned to receive a storage structure 44, lift the storage structure44 to an elevated position, and then shift the storage structure 44 intoengagement with a shifting mechanism 46 coupled to the loading mechanism42. To enable this, the loading mechanism 42 includes a platform 48 witha track 50. The track 50 includes a pair of elongated track elements 52,54. The elongated track elements 52, 54 are spaced apart on the platform48. The loading mechanism 42 also includes a lift mechanism 45 that hasan actuator assembly 64 (shown most clearly in FIGS. 11-13 ). Theactuator assembly 64 is operable to shift the track 50, and inparticular the track elements 52, 54, along an axis 60, i.e., toward andaway from the shifting mechanism 46. The loading mechanism 42 alsoincludes an actuator assembly 66 (shown most clearly in FIGS. 11-13).The actuator assembly 66 is operable to shift the platform 48 along anaxis 62, i.e., up and down relative to the shifting mechanism 46. Theaxis 62 is generally perpendicular to the axis 60. The actuator assembly66 allows a storage structure 44 supported on the platform 48 to beraised toward the shifting mechanism 46, and the actuator assembly 64allows the raised storage structure 44 to be shifted into engagementwith the shifting mechanism 46. The loading mechanism 42 also includes astorage structure 68 extending generally upward along the axis 62. Thestorage structure 68 supports the platform 48 and the actuatorassemblies 64, 66. In addition, while not depicted, a control system maybe connected to the loading mechanism 42 and components thereof. Thecontrol system may be used to control operation of the loading mechanism42, e.g., in coordination with other components of the system 36.

Looking at FIG. 4 , the other end 40 of the system 36 is shown, inaccordance with an embodiment hereof. FIG. 4 depicts a door assembly 70that forms part of the system 36. The door assembly 70 is coupled to theshifting mechanism 46 at the end 40, opposite to the loading mechanism42. The door assembly 70 has a pair of movable doors 71, 73. The doorassembly 70 further includes a door-engaging mechanism 75 (which ispartially obscured in FIG. 4 ) coupled to the doors 71, 73. The doors71, 73 are depicted as sliding doors that are mounted on a track 78. Thedoor-engaging mechanism 75, depending on the configuration, may beoperable to engage and shift, e.g., open and close, the doors 71, 73,e.g., in automated or semi-automated fashion, as described in detail inconnection with FIGS. 14-18 .

Looking specifically at FIG. 5 , an underside of the system 36 is shown,in accordance with an embodiment hereof. FIG. 5 shows the configurationof the shifting mechanism 46 in detail. The shifting mechanism 46includes multiple components that operate in coordination to repositionthe storage structures 44 at different locations. In addition, theshifting mechanism 46 is also designed to interact with the loadingmechanism 42, e.g., by receiving, engaging, and then shifting storagestructures 44 provided by the loading mechanism 42, and is furtherdesigned to interact with the door assembly 70, e.g., by staging storagestructures 44 at the door assembly 70. The shifting mechanism 46 may bedirected by a control system, e.g., as described in connection with FIG.2 . In different embodiments, the control system may be local to thesystem 36 or remote from the system 36, or some combination thereof.

Looking still at FIGS. 3-5 , it can be seen that the shifting mechanism46 includes a track 74 and a plurality of shifting structures 76. Theplurality of shifting structures 76 are coupled to, and are translatablealong, the track 74. In addition, each shifting structure 76 is designedto support and secure a storage structure 44, e.g., one introduced bythe loading mechanism 42. In this respect, the shifting structures 76each include components and/or mechanisms that enable releasablesecurement of the storage structures 44 thereon. The shifting mechanism46 further includes a shifter assembly 80 and a shifter assembly 82. Theshifter assembly 80 is operable to shift the plurality of shiftingstructures 76 along the axis 60, as identified in FIGS. 3-5 . Theshifter assembly 82 is operable to shift the plurality of shiftingstructures 76 along the axis 58, as identified in FIGS. 3-5 . As shownin FIGS. 3-5 , the axis 58 and the axis 60 are generally perpendicularto each other. This orientation of the shifter assemblies 80, 82 allowsthe shifting structures 76, and any storage structures 44 mountedthereon, to translate in different directions within the system 36. Toenable this multi-directional shifting, the shifting structures 76 areable to transfer between the shifter assembly 80 and the shifterassembly 82 during operation of the shifting mechanism 46. This processis described in detail in connection with FIGS. 8-10 .

In one embodiment, the system 36, including the loading mechanism 42,the shifting mechanism 46, and the door assembly 70 are directed by acontrol system. Depending on the configuration, the control system maydirect operation of the components individually, or in coordination(e.g., allowing for simultaneous operation and interaction).

In another embodiment, a control system may direct operation of theloading mechanism 42, the shifting mechanism 46, and/or the doorassembly 70 based on a geographic location of the system 36, or ageographic location of a mobile transport that incorporates the system36. For example, the geographic location of a mobile transport, e.g.,delivery vehicle, may be determined using a global positioning system(“GPS”), wireless communication system, telematics, and/or anotherlocation-tracking technology or system. Based on the locationinformation, the control system may direct the system 36 to performdifferent operations. For example, when approaching a particularlocation, the shifting mechanism 46 may operate to shift a particularstorage structure 44 to the door assembly 70, e.g., to allow a deliverydriver to quickly and easily access objects stored on the storagestructure 44.

Looking at FIG. 6 , the shifting mechanism 46 initially shown in FIGS.3-5 is depicted in isolation, in accordance with an embodiment hereof.FIG. 6 shows how the track 74 extends throughout a staging area 72. Thestaging area 72 is sized to accommodate the storage structures 44 whenmounted on the shifting structures 76, providing sufficient room suchthat the storage structures 44 can shift around the staging area 72during operation of the shifting mechanism 46. The staging area 72 isalso enclosed by a frame 84. In different embodiments, the frame 84 maybe integrated with, and/or form part of, a mobile transport, e.g., adelivery vehicle. The frame 84 includes a track 86 positioned oppositeto the track 74. The tracks 74, 86 may be used in combination tosupport, enclose, and guide the storage structures 44 about the stagingarea 72, e.g., securely during transit of an associated mobiletransport.

FIG. 6 also depicts the shifter assemblies 80, 82 in detail. The shifterassemblies 80, 82 are located adjacent, e.g., directly below, the track74. The shifter assembly 80 extends across opposite sides of theshifting mechanism 46, generally along the axis 60. The shifter assembly82 extends across the shifting mechanism 46 generally along anorthogonal axis, i.e., along the axis 58. The shifter assemblies 80, 82each translate their respective components along these axes 58, 60 toimpart translation forces along such axes 58, 60. In this respect, theshifter mechanism 80, and the shifter mechanism 82, each include aplurality of individual sub-mechanisms that operate to translate theirassociated components along a common axis, e.g., along the axis 60 forthe shifter assembly 80, or along the axis 58 for the shifter assembly82. In the embodiment shown in FIG. 6 , each individual mechanism is abelt-driven mechanism 88. However, different mechanisms that utilizedifferent mechanical, electrical, and/or pneumatic components are alsocontemplated herein. In addition, in different embodiments, each shifterassembly 80, 82 may include any number of belt-driven mechanisms 88 thatextend along the common axis 58 or 60, in spaced relation. This numbermay be selected based on the desired cross-shifting capability withinthe system.

The belt-driven mechanisms 88 of the shifting mechanism 46 may belocated adjacent, e.g., directly below, the track 74, as shown in FIG. 6. The belt-driven mechanisms 88 shown in FIG. 6 each include a belt 85and a plurality of engaging elements 96 (e.g., structures having arecess, indentation, or feature that is C-shaped or U-shaped) mounted onthe belt 85. During operation of a belt-driven mechanism 88, the belt 85is translated in a continuous fashion, e.g., over powered or idlingrollers. This, by association, translates the plurality of engagingelements 96 mounted on the belt 85 along the corresponding axis ofoperation, e.g., the axis 60 for the shifter mechanism 80, or the axis58 for the shifter mechanism 82. The shifting structures 76 each includean elongated extension 90 that extends toward the shifter assemblies 80,82. The elongated extension 90 is configured so that it can be receivedin any of the plurality of engaging elements 96. The elongated extension90 can therefore engage with a plurality of engaging elements 96, andafter doing so, be shifted by the associated belt-driven mechanism 88along the corresponding axis of operation, e.g., the axis 60 for theshifter assembly 80, or the axis 58 for the shifter assembly 82. Thisprocess is described in further detail in connection with FIGS. 8-10 .

Looking at FIGS. 7A-7B, part of the shifting mechanism 46 shown in FIG.6 is provided, in accordance with an embodiment hereof. FIG. 7A depictspart of the track 74, showing how it extends around the staging area 72.FIG. 7A also depicts the shifting structures 76 that translate along thetrack 74 during operation of the shifting mechanism 46. FIG. 7A alsodepicts part of the shifter assembly 80 and the shifter assembly 82,each having their associated belt-driven mechanisms 88, discussed inconnection with FIG. 6 . It should be noted that in differentembodiments, perpendicular shifter assemblies, e.g., such as the shifterassemblies 80, 82 shown in FIG. 7 , may include different numbers ofbelt-driven mechanisms, e.g., such as the belt-driven mechanisms 88, tofacilitate shifting of objects along corresponding axes of operation,e.g., at spaced intervals. In other words, a shifting mechanism may beconfigured so that a desired number of pathways for shifting along oneaxis are provided and a desired number of pathways for shifting alonganother perpendicular axis are provided (e.g., a 2 x 2, 2 x 4, 2 x 8, 4x 4, 4 x 8 or another configuration of orthogonally oriented mechanismsis contemplated herein).

The shifting structures 76 shown in FIG. 7A each include an engagingmechanism 92. The engaging mechanism 92 allows a storage structure 44 tobe securely coupled to the shifting structure 76. To enable this, theengaging mechanism 92 includes a plurality of adjustable, e.g.,depressible, retractable, or actuatable, elements 94. The plurality ofelements 94 extend along opposite sides of each shifting structure 76.In one embodiment, in a resting state, the plurality of elements 94naturally bias outward. This bias may be provided using springs,magnets, and/or other mechanical, electrical, hydraulic, and/orpneumatic actuators integrated with the engaging mechanism 92, indifferent embodiments. The engaging mechanisms 92 are designed to engagea corresponding feature located on a storage structure 44, as describedbelow.

During a shifting operation, a storage structure, such as the storagestructure 44 shown in FIGS. 3-5 , can be coupled to, and shifted on, theshifting structure 76, shown in isolation in FIG. 7B. In one embodiment,each storage structure 44 may include a base 37 with a plurality ofapertures 35 extending along opposite sides of the base 37, as shown inFIG. 7B. The shifting structures 76, one of which is also shown inisolation in FIG. 7B, each include the engaging mechanism 92, which hasthe plurality of elements 94 located along opposite sides of theengaging mechanism 92, their position corresponding to the location ofthe plurality of apertures 35 formed in the base 37. With thiscorresponding configuration, the shifting structure 76 is able toreceive, engage, and support the base 37, and by association, thesupport structure 44 coupled thereto, during a loading and shiftingprocess, an example of which is described below.

The following illustrates an example process of loading, engaging, andshifting the example storage structure 44. First, the storage structure44 is positioned for engagement with the shifting structure 76, e.g.,using the loading mechanism 42. In one instance, the loading mechanism42 advances the storage structure 44 onto the engaging mechanism 92,e.g., by shifting the track 50 shown in FIG. 3 toward the engagingmechanism 92. This interaction actuates, e.g., depresses, the pluralityof elements 94 on the engaging mechanism 92 (the plurality of elements94 may alternatively be retracted through operation of componentsinternal to the engaging mechanism 92). Then, once the storage structure44 is positioned so that a plurality of apertures (e.g., such as theapertures 35 shown in FIG. 7B) on a base (e.g., such as the base 37shown in FIG. 7B) of the storage structure 44 are aligned with theplurality of elements 94 on the engaging mechanism 92, the plurality ofelements 94 are extended, e.g., either through retracting the track 50to de-engage it from the plurality of elements 94, or otherwise throughactuating or de-actuating elements internal to the engaging mechanism92. This results in the plurality of elements 94 extending outward, andinto the plurality of apertures at the base of the storage structure 44.This engagement couples the shifting structure 76 and the storagestructure 44 together, allowing the shifting structure 76 to translateabout the track 74 in tandem with the storage structure 44.

Looking at FIGS. 8-10 , the belt-driven mechanisms 88 associated withthe shifter assemblies 80, 82 are shown, in accordance with anembodiment hereof. FIGS. 8-10 depict different perspectives of thebelt-driven mechanisms 88 associated with the shifting mechanism 46shown in detail in FIG. 6 .

Looking specifically at FIG. 8 , it can be seen that the belt-drivenmechanisms 88 each include a similar set of components that supportoperation thereof. For example, each belt-driven mechanism 88 includes abelt 95. In addition, each belt 95 includes a plurality of engagingelements 96 attached to the belt 95. The plurality of engaging elements96 each have an opening 98 that is oriented perpendicular to the generaldirection of translation of the belt 95. Due to this configuration, anobject, e.g., the elongated extension 90 of the shifting structure 76shown in FIG. 6 , is able to be received in the opening 98 of theengaging element 96, in a direction perpendicular to the generaldirection of translation of the belt 95. This direction along which theobject, e.g., elongated extension 90 shown in FIG. 6 , can enter/exitthe opening 98 is shown by the arrows 100 provided in FIG. 9 .

Looking specifically at FIG. 9 , once an object, e.g., the elongatedextension 90 shown in FIG. 6 , is received in the plurality of engagingelements, sides 102, 104 of the engaging element 96 (only one pair ofwhich are identified in FIG. 9 for explanation purposes) are able totranslate a force from the belt 95 to the object, e.g., elongatedextension 90, thereby shifting it in a general direction of translationof the belt 95. This causes the associated shifting structure 76 and anystorage structure 44 supported thereon to be shifted along the generaldirection of translation of the belt 95. Depending on which belt-drivenmechanism 88 is performing the shifting, the translation occurs alongthe axis 60, or the axis 58, as identified in FIGS. 8-10 .

Looking specifically at FIGS. 9 and 10 , it can be seen how thebelt-driven mechanisms 88, and specifically those oriented perpendicularto each other, are positioned at different heights along the axis 62.This configuration allows an object, e.g., the elongated extension 90,to be translated along one axis 60 using an engaging element 110 of onebelt-driven mechanism 106, and then be transferred into aperpendicularly oriented engaging element 112 located on anotherbelt-driven mechanism 108 that is oriented perpendicular to thebelt-driven mechanism 106. The object can then be shifted by theengaging element 112 along the axis 58, out of the engaging element 110,and along a new direction. The reverse is also possible, depending onthe direction of rotation of the belts 95. This transfer, or “handoff”process for the object, e.g., the elongated extension 90 shown in FIG. 6, allows for continuous shifting of the storage structures throughoutthe staging area 72, both along the axis 58 and the axis 60. FIGS. 8-10further depict a series of actuators 114 coupled to the belt-drivenmechanisms 88 that translate the associated belts 95 during operation ofthe shifting mechanism 46.

Looking at FIGS. 11-13 , the loading mechanism 42 depicted originally inFIG. 3 is shown in isolation, in accordance with an embodiment hereof.FIG. 11 depicts a perspective view of the loading mechanism 42. FIG. 12depicts an enhanced view of part of the loading mechanism 42. FIG. 13depicts the platform 48 of the loading mechanism 42. The loadingmechanism 42 shown in FIGS. 11-13 is intended to represent one exampleconfiguration, and numerous others capable of achieving the samefunctionality are contemplated herein.

The loading mechanism 42 shown in FIGS. 11-13 includes a storagestructure 68, a platform 48, and a lift mechanism 45. The platform 48includes a track 50 that includes a pair of elongated track elements 52,54 that are spaced apart on the platform 48. The track elements 52, 54are translatable along the axis 60, i.e., generally toward and away fromthe storage structure 68, through operation of the actuator assembly 64,shown in FIG. 12 . The lift mechanism 45 includes an actuator assembly66 that is operable to translate the platform 48 along the axis 62,i.e., between a lowered position and a raised position. The storagestructure 68 extends generally along the axis 62. The loading mechanism42 also includes a shifter assembly 116 that is operable to shiftcomponents along the axis 60, thereby allowing an object, e.g., thestorage structure 44 shown in FIGS. 3-5 , to be shifted from the track50 into a staging area, e.g., where a shifting mechanism, such as theshifting mechanism 46 shown in FIGS. 3-5 , is located.

Looking still at FIGS. 11-13 , the lift mechanism 45 is designed so thata storage structure, e.g., the storage structure 44 shown in FIGS. 3-5 ,can initially be loaded onto the platform 48 where it is supported bythe track 50 and track elements 52, 54 thereof. The actuator assembly 66may then be operated to translate the platform 48, including the track50, along the axis 62, i.e., from a lowered position to a raisedposition. The raised position, generally speaking, may be one thataligns the track 50 and track elements 52, 54 thereof with the shifterassembly 116 shown in FIG. 11 . The actuator assembly 64 can then beoperated to shift the track 50, e.g., with the storage structure 44supported thereon, along the axis 60, i.e., shifting it towards theshifter assembly 116 shown in FIG. 12 . The shifter assembly 116 maythen be operated to further shift the storage structure into a stagingarea, e.g., the staging area 72 with the shifting mechanism 46 shown inFIGS. 3-5 . In different aspects, the shifter assembly 116 may directlyengage, and/or operate in coordination with, the track 50 and/or thetrack elements 52, 54.

Looking at FIG. 13 , it is shown how the track elements 52, 54 extendacross the platform 48. In addition, the track elements 52, 54 arespaced apart on the platform 48, allowing them to support the base of astorage structure, e.g., the storage structure 44 shown in FIGS. 3-5 .The track elements 52, 54 are each coupled to a corresponding guidetrack 118, 120 that is fixed to the platform 48. During operation of theactuator assembly 64, the track elements 52, 54 can shift along theircorresponding guide track 118, 120, i.e., back and forth along the axis60. For example, when the track 50 is in alignment with the shifterassembly 116, this actuation allows a storage structure supported on thetrack elements 52, 54 to be shifted toward, e.g., into engagement with,the shifter assembly. The track elements 52, 54 also each include acorresponding surface 124, 126 that is angled, or slanted, relative tothe axis 60 along which the track elements 52, 54 slide. Theseangled/slanted surfaces 124, 126 allow the track elements 52, 54 toprogressively engage components located on a shifting structure, e.g.,such as the engaging elements 94 located on the engaging mechanism 92forming part of the shifting structure 76 shown in FIG. 7A. The platform48 of the loading mechanism 42 also includes a door 128. The door 128 ispivotably coupled at an end of the platform 48. The door 128 is pivotalbetween a position that is generally parallel with the axis 62 and aposition that is generally parallel with the axis 60. The door 128 canbe used to secure/enclose structures positioned on the platform 48during operation of the lift mechanism 45.

Looking still at the loading mechanism 42 shown in FIGS. 11-13 , it canbe seen how the actuator assembly 64 and the actuator assembly 66 eachinclude different components that support their operation. For example,this may include belt-driven mechanisms, linear actuators, powercomponents, and/or control components, among other possible components.In the embodiment shown in FIGS. 11-13 , the actuator assemblies 64, 66each include a corresponding belt-driven mechanism 122, 123 that is usedto translate components. The belt-driven mechanisms 122, 123 eachinclude a belt, at least two rollers over which the belt is positioned,and at least one rotational actuator that rotates the belt duringoperation of the belt-driven mechanisms 122, 123.

In different embodiments, the operation of the actuator assemblies 64,66 and the shifter assembly 116 shown in FIGS. 11-13 may be directed bya control system. The control system may be connected to each of theassemblies 64, 66, 116, and may be local to the loading mechanism 42and/or an associated mobile transport, and/or remote from the loadingmechanism 42 and/or an associated mobile transport. The assemblies 64,66, 116 may operate in automated or at least partially automatedfashion, e.g., at the direction of the aforementioned control system. Inone instance, the operations may be directed by a remote computingdevice that monitors and controls multiple components, e.g., theshifting mechanism 46 and door assembly 70.

Looking at FIGS. 14-18 , a door assembly 130 is provided, in accordancewith an embodiment hereof. The door assembly 130 shown in FIGS. 14-18 isintended to represent one example configuration, with numerous othersbeing contemplated herein. FIG. 14 depicts one side 132 of the doorassembly 130. FIG. 15 is an enhanced depiction of part of the doorassembly 130 shown in FIG. 14 . FIG. 16 depicts another side 134 of thedoor assembly 130. FIG. 17 depicts part of the door assembly 130 shownin FIG. 16 . FIG. 18 is another enhanced depiction of the door assembly130 shown in FIG. 16 . In one embodiment, the door assembly 130 may beintegrated into a mobile transport, such as the vehicle 174 shown inFIG. 19 . This integration may be provided through integralassembly/design, or through retrofitting an existing door assemblylocated in a vehicle.

Looking at FIG. 14 , the door assembly 130, and in particular, the side134 of the door assembly 130, is shown, in accordance with an embodimenthereof. The door assembly 130 includes a frame 140. The door assembly130 also includes a pair of doors 136, 138 that are slidably coupled torespective tracks 142, 144 that extend along a top of the frame 140. Thedoor assembly 130 further includes a door-shifting mechanism, variationsof which are shown in FIGS. 16 and 18 . In one embodiment, thedoor-shifting mechanism is an actuator 148, as shown in FIG. 18 , thatoperates to shift the doors 136, 138 open and closed, e.g., at thedirection of a control system. In another embodiment, the door-shiftingmechanism includes movable components, e.g., as shown in FIG. 16 , thatoperate to engage and translate the doors 136, 138 between a closedconfiguration and an open configuration, e.g., at the direction of acontrol system.

The door assembly 130 may be configured to operate in automated orsemi-automated fashion. For example, a control system may becommunicatively connected to components of the door assembly 130. Inaddition to controlling the door assembly 130, the control system maydirect other loading, shifting, and/or staging components, e.g.,allowing these systems to operate in coordination. This automated orsemi-automated operation may impart greater efficiency to a loading,staging, and delivery sequence, e.g., one performed in a logisticsnetwork operation. In one instance, the door assembly 130 may beintegrated into a delivery vehicle. Then, while the delivery vehicletravels a delivery route, a control system directs a shifting mechanism,such as the shifting mechanism 46 shown in FIGS. 3-5 , to operate andre-organize a plurality of storage structures, e.g., the storagestructures 44 shown in FIGS. 3-5 , positioning a particular storagestructure at the door assembly 130. The particular storage structure maybe staged based on the vehicle approaching or arriving at a deliverydestination associated with one or more objects stored on the storagestructure. Upon arrival, the door assembly 130 may open in automated orsemi-automated fashion to provide efficient access to the staged storagestructure. This process may be repeated as the vehicle makes multipledelivery stops and thereby increase the speed and efficiency of adelivery operation.

Looking at FIG. 15 , part of the door assembly 130 is shown, inaccordance with an embodiment hereof. FIG. 15 shows the doors 136, 138coupled to the frame 140 at the tracks 142, 144. The tracks 142, 144 mayeach include an elongated slot (not shown in FIG. 15 ) through whichguides 150, 152 are respectively extended, and supported, allowing thedoors 136, 138 to slide back and forth, e.g., in response to operationof a door-shifting mechanism.

Looking at FIG. 16 , the side 134 of the door assembly 130 is shown, inaccordance with an embodiment hereof. In one embodiment, the doorassembly 130 may be integrated into a vehicle, where the side 134 isoriented to face a storage area in the vehicle, and the side 132 isoriented to face a cab in the vehicle. In a further embodiment, thestorage area may include a shifting mechanism, e.g., such as theshifting mechanism 46 shown in FIGS. 3-5 , that stages storagestructures at the door assembly 130. The embodiment depicted in FIG. 16includes a door-shifting mechanism 147 that is configured to engage andoperate the doors 136, 138, as discussed further below.

The door-shifting mechanism 147 encompasses a series of elements thatare used to open and close the doors 136, 138, e.g., in automated orsemi-automated fashion. The doors 136, 138 each include a respectiveengaging element 154, 156, as shown in most detail in FIG. 17 . Thedoor-shifting mechanism 147 also includes engaging elements 160, 162that are coupled to respective distal ends 161, 163 of movable members,e.g., multi-axis arms, 155, 157. The movable members 155, 157 areconnected to one or more actuators and control components, and mayinclude hinges, linearly-translating elements, and pivot or ball joints,among other features.

Through operation of the door-shifting mechanism 147, the engagingelements 160, 162 can be shifted in different directions, e.g., alongthe axis 164, 166, and/or 168, depending on the configuration. Forexample, in one embodiment, the engaging elements 160, 162 may beshiftable along the axis 166 and the axis 168, allowing them totranslate into a coupled configuration with the engaging elements 154,156. The engaging elements 160, 162 can be shifted into contact with theengaging elements 154, 156 through translation along the axis 168, andthen the coupled engaging elements 154, 160 and 156, 162 can be shiftedalong the axis 166, thereby translating the doors 136, 138 between anopen configuration and a closed configuration, depending on thedirection of actuation. The engaging elements 154, 156, 160, 162 may bemale-female couplings, magnetic mechanisms, latching mechanisms, oranother form of mechanical, electrical, and/or pneumatic attachmentmechanism. In additional embodiments, the engaging elements 160, 162 maysimply remain fixed to the engaging elements 154, 156, such thatshifting them into contact is not necessary to translate the doors 136,138.

Looking at FIG. 17 , part of the door assembly 130, located on the side134, is depicted, in accordance with an embodiment hereof. FIG. 17 moreclearly depicts the engaging elements 154, 156 mounted on the adjacentdoors 136, 138. In this example embodiment, the engaging elements 154,156 each include a recess 170, 172 that is shaped to receive acorresponding extension located on the engaging elements 160, 162 shownin FIG. 16 . In the example of the door assembly 130, the extensions arethe engaging elements 160, 162 that are insertable into the recesses170, 172 along the axis 168, thus allowing a force applied by theengaging elements 160, 162 along the axis 166 to shift the engagingelements 154, 156, and by association, the doors 136, 138.

Looking at FIG. 18 , the door assembly 130 is again shown, but with anactuator 148 that forms part of a door-shifting mechanism 145, inaccordance with an embodiment hereof. In some embodiments, thisconfiguration may be used for translating the doors 136, 138 along thetracks 142, 144 shown in FIG. 15 , e.g., between a closed configurationand an open configuration. In one example, the actuator 148 may formpart of a belt-driven assembly coupled to the frame 140 and to the doors136, 138. In addition, or in the alternative, the movable members 155,157 of the door-shifting mechanism 147 may be installed as shown in FIG.16 , and controlled/actuated to engage, open, close, and/or disengagethe doors. In either instance, the door-shifting mechanisms 145, 147 mayoperate in automated or semi-automated fashion, e.g., at the directionof a control system.

The vehicle 174and the systems integrated therein may be manually operated,autonomously operated (e.g., being driverless), and/or may besemi-autonomously operated. In one aspect, the vehicle 174 may beretrofitted from its original configuration to include the loadingmechanism 176, the shifting mechanism 178, and the door assembly 130,e.g., to upgrade its automation capability for use in a logisticsnetwork operation.
